Hey guys, many people who have jailbroken their devices on 4.2.1 with Redsn0w, may have turned off or re-booted their device, and couldn't be able to get it out of teatherd mode. This is because timing and getting it 100% right is Key. So here are the instructions again:- Make sure your device (iPod touch, iPhone or iPad) is on the apple logo and connected to your PC or Mac.- Open Redsn0w, find your firmware (see download links below) then press next.- Un-tick 'Install Cydia' and then tick 'Just boot teatherd right now'. Then press next.- Now, press both the sleep and home button on your device, till the screen goes black. The next part will have to be done VERY quickly!- As soon as your screen has gone black, keep holding the sleep button and press next on Redsn0w.- On Redsn0w, follow the on-screen guide and then finally once ALL steps are done, Redsn0w will start doing something and then your device may blink white and then the pineapple logo will appear for 30 secs - 1min on your device.

PROBLEMS:- If you have completed the steps that redsn0w has told you, and you get this error 'No device detected, you probably misunderstood the instructions', you must try all the steps I told you again and make sure your timing is PRECISE.- If your device is on the apple logo, and you open up iTunes and see this ' error OxE8000065', do not worry nothing as happened, iTunes is just confused, it will dissapear and be back to normal once your device is out of the teather.
